When using GParted to format an ext4 USB Flash drive, it seems sufficient to select Parition > New, rather than Device > Create Partition Table. That's good because after selecting "create partition table" it doesn't seem right to select msdos and none of the other choices seems obviously right. Instead, I proceeded to use Parition > New and then the ext4 selection.
What happens in this case?
A. Is there no partition table on the device?
B. Is there some default partition table and if so, what kind?
C. Something else?
Best Answer
If a partition table does not exist and is not created, then using Partition -> New will format the entire device with the selected file system.
See GParted Manual - Creating a Partition Table to learn about the two most popular partition tables (msdos and gpt).
